We already have many of the technologies needed to fight super pollutants. Given how harmful these super pollutants are on our environment, it only makes sense to use these existing technologies to reduce our emissions and slow climate change before it is too late.

What's needed is an inclusive, political settlement -- with all stakeholders included -- that ends the fighting and stops the region from meddling, something we missed the mark on years ago. Until we do that, any Afghan security deal will remain elusive.

Immunity for U.S. troops post-2014 isn't going to happen. It's a political non-starter. No Afghan presidential candidate, queuing for the April 2014 elections, can support it, nor do the Afghan people want immunity for foreign troops.

While Dr. King's progressive dreaming of a world where racial and economic equality is commonplace may have been radical then, his most radical thinking -- and what would still get him in trouble with federal authorities to this day -- is his messaging on nonviolence.

These bipartisan bills in the House and the Senate are must-pass bills, if primarily for the return on investment. To fail this opportunity is to pass on serious financial returns and it is a pass on a healthier environment for the American people. We cannot fail. The time for bipartisanship is now.

As the elections signified, it is the Iranian people who will ultimately shape the destiny of Iran. And it is the Iranian people who have borne the brunt of sanctions, and it is these human impacts that must always be at the forefront of U.S. sanctions policy considerations.

A handful of Democratic and Republican senators are considering a rewrite of 60 of the most consequential words to ever pass through Congress: The Authorization for Use of Military Force, which is enabling a system of eternal warfare.

The financial institutions' focus on generating economic growth without ensuring the concomitant increase in jobs, and the inequality this generates, is partly to blame for the waning public support for global economic integration.

Without question this town has a problem with racism. It's evident in how white the branches of the federal government remain, how geographically divided D.C. is along racial lines. Few of these inequities, however, can be as quickly corrected as the Washington Redskins' racist moniker.

There is nothing radical about closing schools. A "radical" approach would have been for Rhee to tackle poverty and unemployment in D.C., a far more effective method of advancing early childhood education.

How would the NRA, who suggested after the Sandy Hook shooting in Connecticut that we provide armed guards in every school across America, at a cost of nearly $8 billion per year, respond to New Jersey's shooting?

America is witnessing some of its highest income inequality and lowest social mobility rates ever. If we are to fix any of this, it is best that we start at home, in our back yard, and in our nation's capital. And that begins with the Anacostia.

What we say, do, and eat has global implications, and on these three major security frontiers we must do better: religious, food and climate security. Each of us has a role to play, and each of us is capable of making a difference.

The Democratic Party continues to be the party of hope and change, but not in the way you think. People are hopeful because this party represents the changing face of America. We are a different people now than we were in the 1800s, or even the 1900s, and we require a party that gets that, that reflects that.

Do Americans realize that under a Ryan economic regime, tens of millions of our poor neighbors would be dropped categorically and coldly to the curb, with no support whatsoever from the very system that our forefathers and mothers set up to ensure that America would prosper?

We know from the countless stories of many marginalized American communities -- from LGBT communities to Latino immigrants -- that bullying is practiced, promulgated and promoted in America. Why are we so good at it?
